A deep conditioning treatment is particularly beneficial after chemical services or prolonged sun exposure because these factors can significantly alter the hair's integrity. Chemical services often involve processes that can strip the hair of its natural moisture and weaken it, making it more susceptible to damage. Similarly, prolonged sun exposure can lead to dryness, brittleness, and loss of essential nutrients.

Recommending a deep conditioning treatment in these situations helps to replenish moisture, strengthen the hair, and restore its overall health and appearance. This treatment infuses the hair with beneficial ingredients that can penetrate the hair shaft, providing necessary hydration and repair.

The other options are less optimal because, while conditioning can be beneficial in various situations, not every shampoo requires a deep conditioning treatment, and it is not solely reserved for when hair is oily or at a client’s mere request without considering their specific hair needs and condition. This approach ensures that the treatments provided are tailored to effectively address the hair’s condition and improve its health over time.
